How does potassium nitrate remove stumps?

Can you build up dirt around a tree?

How much fill can you put around a tree?

Raising the Grade: Most young, vigorous trees can tolerate shallow fills of up to four inches if the fill is sandy. The same amount of clay fill, however, usually causes tree decline. Certain species, however, such as beech, yellow poplar, pines, and dogwood are very sensitive to even small amounts of a sandy fill.

What do you put around the base of a tree?

Can I pour concrete around a tree?

Covering this area with concrete is likely to cause the death of the tree by physically damaging the roots and by inhibiting oxygen and water from reaching the roots. Additionally, the roots of the tree have the potential to damage/crack the concrete as they grow trying to reach water and oxygen.
